SPECIFICATION forming part of Letters Patent No. 624,283, dated May 2, 1899.

' Application filed June 15,1898. Serial No. esaeia. (No model.)

To all whom it may concern:

Be it known that 1, JAMES ANDREW YAR- TON, of Kansas City, in the county of Wyandotte and State of Kansas, have invented a new and Improved Oil-Gas Lamp, of which the following is a full, clear, and exact description.

My invention relates to an improvement in that class of lamps which burn gas, but make their own gas from oil. I have also herein shown it used in combination with a burner having an incandescent mantle.

My invention comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming a part of this specification, in'which is shown a vertical sectional view of my device.

The oil is contained in a tank or reservoir A, provided with two pipes at and a, connecting, respectively, with the top and bottom thereof. These pipes also connect with a vertical pipe B, preferably provided with a hook C or other convenient means by which it may be suspended. The upper pipe at connects the pipe B and the tank A, permitting any gas which may collect in the pipe B to escape into the upper part of the reservoir,thns equalizing the pressure of the gases in each, and thereby maintaining uniform conditions as to pressure upon the oil flowing from the tank to the place'of use. This pipe also acts as a support to the tank. It is to be understood that either the cover of the reservoir is not to fit air-tight on the reservoir or is to be provided with a relief-opening or vent, permitting air to enter as the oil. is drawn out. The lower pipe at, which is connected by a vertical extension to the bottom of the tank-A, extends upwarda short distance through and above said bottom, at which point the oil for use is taken in, leaving a place for settling of sediment on the bottom of the tank around the extended tube. This prevents any sediment from entering the pipe a. This latter pipe a is also connected at its other end to a T-fitting Z7, which forms a part of the vertical pipe B. Within the fitting is placed a 'hollow cone D, with its larger end down and connected to the fitting of the upper end of the pipe-section B, which screws into the lower end of said fitting. The upper end of the cone D, which is the smaller and is open, extends to some little distance above the pipe a, leaving another settling-place for the sedi-' ment about it and at the same time securing uniformity of pressure upon the oil at the point of its entrance into the pipe B, and hence evenness and regularity'of its movement-or onfiow into the valve-casing E.

The valve-casing E is of peculiar form and consists of a casting havinga recess or chamber E in its upper end adapted to receive the lower end of the pipe-section B. It is also provided at one side witha lateral passage connecting with said chamber, adapted to receive a valve, said passage being a short dis tance above the bottom of the chamber, so that another settling-place for sediment therein is had. The stem F of the valve is threaded into a laterally-extending boss e on the casting, at the other end of which is a stuff ing-box to prevent leakage, the end of the stem being provided with a hand-wheel F or other meansv by which the valve may be adjusted.

The valve proper consists of a head F upon the inner end of the stem F. This head is of pointed or conical shape and enters one portion of the lateral passage before referred to, so as to close the same. The laterally-extending boss e, which is on this side of the casing and through which the lateral passage extends, has a tube G screwed therein, forming a part of a peculiarly-constructed gas-generator. This generator consists of a tube extending laterally and having its outer extremity bent in U shape, the return part being bent slightly upward over the point where left in the generator, if any, settles in-the trap made by thedam andis here held. until vaporized. This insures a condition making clogging of the nozzle or tip by flow of oil into it impossible. At this point the tube is preferably provided with atip g, forming a nozzle to concentrate the gas-discharge. An important feature of this generator is a core G, inserted in the tube and made of copper Wire twisted and Woven in such a manner as to bring as many of the wires as possible composing it into contact with the walls of the tube when so inserted. This core is twisted or Wovenand inserted inthe pipe with such a degree of compactness as to regulate the onward flow of the oil, and at the same time all or nearly all of its wi'res'coming in contact with the walls of the tube the heat will be disseminated throughout the mass to be vaporized. Copper wire is used most effectively because of its great conductivity of heat and also for its non-corrosive properties, two considerations of the utmost importance. This core-bearing tube is adaptedv to pivot upon the straight section G, which is attached directly to the valve-casing E, thus allowing the othersection G to be swung over the lamp or at one side thereof, as desired, so that'the chimney or other parts of the burner may be readily placed'thereon or removed. Without such provision it would be a difficult matter to remove the chimney from the ordinary burner if the generator is kept close down-to the chimney, as the chimney must be raised to remove it from the burner.

Beneath the portion of the valve-casing last; described is an extension which vis provided with a curved passage E At its lower end it is-connected with the mixing-pipe H-, audits upper end is adapted to receive the discharge of gas from the generator. The pipe H. extends downwardly, then horizontally, and then upwardly, terminating in the nipple H, adapted to receive a nipple or socket-piece I, which is large enough to slip over the outside of the nipple H. This socketpieceI is provided with arms L, extending outward therefrom and adapted to support the'chimney M and the other parts of the burner. This construction provides a large draft area between the burner proper and the-chimney. The socket-piece Iextends upwardly within the burner, and at its upper end is provided with a cap K, composed of gauzev or a perforated metal plate. An incandescent mantle J is also suspended in any convenient manner over the cap K.

In operation the gas-generator is heated by an alcohol-torch or other means, and then the valveF'is opened, so that the oil can pass into the generator.. The heated generator willathen vaporize the oil, and the gas thus formed'will be discharged throughthe nozzle 9 into the passage E It will be conveyed thence through the tube H to the burner and will-be ignited'at the mantle J. ,Once ignited the heat from the lamp will provide a continuousheatingof the generator, so as to'effectually vaporize the oilzas it passes-through the generator-pipe, thereby furnishing a perpetual supply of gas for illumination.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A valve-casing for oil-gas lamps, comprisingabodyhavingachamberformed therein adapted to receive an oil-supply pipe, and a lateral intersecting passage adapted to re- .ceive at one end avalve and its stem, and at the other a gas-generator, said casing-body also having a separate passage therein adapted to receive the mixing-pipe atone end and the discharge from the generator at the other.

In an oil-gas lamp, a valve-casing, comprisingabodyhavingachamber formed therein adapted to receive an oil-supply pipe and having a laterally-intersecting passage adapted to receive-at one end a valve and its stem, and at the other enda gas-generator, a threaded bar in the lateral passage, carrying a valve, said casing-body also having a separate pas sage therein adapted to receive the mixingpipe atone end and the discharge from the generator at the-other, and. said mixing-pipe being attached atone end to the casing, a burner attached to the other end of the mixing-pipe, and: a gas-generator connected at one end with the lateral passage in the easing and discharging at its other end into the .mixing passage in: the casing, the body of a valved supply-tube, of a recurved generator extending fromand revolubly held within saidsupply-tube, said generator being provided with adrop or bend forming a-settlingchamberwhich is located immediately over the burner, an. open-ended mixing-pipe, the upperend. of said pipe forming an interrupted continuation of said.- recurved generator, and
